Fig. 1 is a block diagram schematically illustrating a system 100 for applying pressure to a lower part 106 of the body of an individual 101 according to an embodiment. The system includes a chamber 102 and means 103 for adjusting (increasing or decreasing) and maintaining the pressure inside the chamber 102. An example of the means 103 is a negative feedback control system described below.

The chamber 102 includes an opening 104 along a vertical axis to receive the lower part 106 of the body. According to one embodiment, the chamber 102 may include a soft or rigid cover.

With respect to the chamber 102 having a soft cover, the soft cover can be inflated or deflated as appropriate. The chamber 102 may take a hemispherical shape when the soft cover inflates. Fig. 1 illustrates an embodiment in which the chamber 102 includes an upper part of a sphere with a flat cross-section as a base 108 of the chamber 102. The base 108 supports the individual 101 standing or sitting. The soft cover may be made of a sufficiently tight fabric. When deflated, the soft cover may allow the lower part 106 of the body to be positioned inside the opening 104. The opening 104 may include an elliptical shape and a flexible fabric to accommodate various waist shapes of the lower part 106 of the individual's body. The height of the soft fabric cover can be altered using straps to pull down the top. For example, opening 104 may include a rigid ring (not shown) surrounding the waist or torso of the individual 101. In this way, the height of the chamber 102 can be adjusted by raising or lowering the rigid ring.

A bar (not shown) may encompass the fabric cover below the waist of the individual 101. The bar prevents the fabric cover from expanding to a spherical shape, thereby maintaining the cover near the torso of the individual 101, allowing a comfortable turn of the arm. Similarly, the rigid cover can prevent the arms of the individual 101 from touching the rigid cover while the individual 101 is moving (walking or running) by means of a saddle shape.

System 100 may also include a rear entry gateway (not shown) that has a step to facilitate entry to and exit from chamber 102. In chamber 102 that has a soft cover, the gateway can be used as a means to keeping the soft cover up in an uninflated state so that it is easier to secure the seal 110 to the individual 101. The gangway can also serve as a safety platform in the case where the chamber cover 102 is broken ( in the case of cloth) or break (in the case of a hard cover). The gangway may also include tie bars for the individual 101 to grip in the event of a fall.

With respect to the chamber 102 that has a hard cover, the chamber 102 may include a door (not shown) that opens for the individual 101 to enter and exit. The door can be opened by swinging to the side, swinging down or sliding. The door can be composed of fabric over a tightly sealed closed zipper. The opening 104 can be created by separating two halves of the chamber 102 and bringing them together again as a shell, or a cockpit. In addition, the height of the hard cover can be adjusted based on the height of the individual 101.

A seal 110 is provided between the lower part 106 of the body and the opening 104 at or near the torso or waistline of the individual 101. According to one embodiment, the seal 110 includes multiple openings / leaks around the torso of the individual 101 for to cool the individual 101 and to better control the pressure distribution around the torso of the individual 101. For example, the leaks placed in front of the stomach of the individual 101 help with the stomach swelling due to the bulging of the flexible waist seal under pressure. Said deliberate leaks can be implemented by sewing non-hermetic fabrics, or by forming holes in the cover or in the fabric of the chamber 102. The seal 110 may be made of a substantially hermetic material and / or a non-hermetic fabric. Seal 110 can be implemented with a skirt, pants or a combination of both.

According to one embodiment, the seal 110 may include detachable seals by means of zippers, a kayak-style fixation on a rigid edge that is fixed to the deck, clamps and deformable loops. The seal 110 may include means for anchoring to the lower part 106 of the individual's body and means for attaching to the opening 104. The anchoring means may include, for example, velcro straps that extend around the thighs for adjustment of Different thigh widths, a belt that keeps the seal anchored in the hip bone. The anchoring means can also include a high friction material that is sealed against the user and remains anchored due to a high coefficient of friction. Seal 110 can be breathable and washable. According to another embodiment, the seal 110 can also be sealed to the individual's chest. For example, seal 110 may include a skirt type seal.

An exercise machine 112 may be housed inside the chamber 102. The exercise machine 112 may be, for example, a treadmill having an adjustable height, inclination and speed. The height and position of the exercise machine 112 can be adjusted based on a dimension of the individual 101. People with ordinary skill in the art will appreciate that the treadmill shown is not intended to be limiting, and that other exercise machines can be used. exercise without departing from the inventive concepts disclosed herein. The camera 102 can be used without any machine as a means to improve the jumping capacity or general movement.

The means 103 for adjusting and maintaining the pressure inside the chamber include an intake system 114, an extraction system 116, a control panel 118, a pressure sensor 120 and a processor 122.

The intake system 114 includes an inlet port 124 for receiving a gas (eg, air), a pressure source 126 (pump) and an outlet port 128. The gas flow from the pressure source 126 may not be regulated. Pressure source 126 can be activated or deactivated. According to another embodiment, the pressure source 126 may include a variable fan speed that can be adjusted to control the flow of incoming air to the chamber 102. The pressure source 126 pumps gas from the inlet port 124 to the outlet port 128 . The output port 128 is also an input port of the chamber 102. The gas is pumped to the chamber 102 through the output port 128.

The extraction system 116 includes an inlet port 130 for receiving gas from the chamber 102, a pressure regulating valve 132 and an outlet port 134 at ambient pressure. The pressure regulating valve 132 controls the exhaust flow from the chamber 102. The inlet port 130 is an outlet port of the chamber 102. The gas leaves the chamber 102 through the outlet port 134. According to another embodiment, a safety exhaust port (not shown) may be connected to chamber 102 to allow gas to exit chamber 102 in case of an emergency or a system failure.

The control panel 118 includes a user interface system to allow the individual 101 or an operator to interact with the system 100 through the processor 122. For example, the individual 101 may use a touch screen interface (not shown) in the control panel 118 for programming the pressure inside the chamber 102, and the speed, inclination and height of the exercise machine 112. The control panel 118 can also be used to calibrate the individual 101 for a correct body weight. The calibration process is described in more detail in Fig. 6.

The pressure sensor 120 is connected to the chamber 102 to measure a pressure difference between the pressure inside the chamber 102 and the ambient pressure. People of ordinary skill in the art will appreciate that the pressure sensor 102 shown is not intended to be limiting and that other types of pressure transducers or pressure measurement sensors can be used without departing from the inventive concepts disclosed herein. Pressure sensor 120 communicates its measurements to processor 122.

The processor 122 communicates with the control panel 118 and the pressure sensor 120 to control the pressure source 126 and the pressure regulating valve 132. An example of the processor algorithm 122 is illustrated in Figs. 3 and 4. In this configuration, the processor 122 receives an input from the control panel 118. For example, the inlet may include a desired pressure inside the chamber 102 or a desired body weight of the individual. The processor 122 operates the pressure source 126 and the valve 132 regulated using a loop, a circuit or a negative feedback system, as illustrated in Figs. 3 and 4. The processor 122 monitors the pressure inside the chamber 102 with the pressure sensor 120. Based on the measurements from the pressure sensor 120 and the input from the control panel 118, the processor 122 sends an actuation signal to the regulated valve 132 and / or the pressure source 126 to increase or decrease the exhaust flow through the chamber 102 in order to keep the pressure inside the chamber 102 as close as possible to the desired pressure received from the control panel 118. The pressure (positive or negative) inside the chamber 102 produces an upward or downward force on the individual 101, which results in a lighter or heavier sensation.

The processor 122 can also communicate with the exercise machine 112. The processor 122 can receive input parameters from the control panel 118 for the exercise machine 112. For example, the exercise machine 112 may include a treadmill with a speed or an inclination adjusted by the processor 122 based on the pressure detected inside the chamber 102.

System 100 is also controlled to maintain various performance parameters, such as a constant stride frequency. A sensor can be placed on the treadmill to detect the impact from the feet of the users on the treadmill and compare it with subsequent values to measure the length of time between strides. Then the machine can adjust pressure, tilt, speed, etc. to maintain a specific stride frequency.

System 100 includes an acceleration / deceleration sensor coupled to individual 101 that detects whether the user is accelerating or decelerating. People with ordinary knowledge in the art will recognize that there are many ways to implement such a sensor. The processor 122 receives the measurement from the acceleration / deceleration sensor and can send a signal to increase or decrease the speed of the treadmill in response to the measurement in combination with an increase or decrease in the pressure inside the camera 102.

The processor 122 may also include data storage (not shown), such as a database that stores various executable programs that can be selected or programmed by the individual 101 or by an operator through the control panel 118. The data storage may include a data repository that can be used to control the system 100. For example, while receiving data from the sensors (including the pressure sensor, the individual's performance sensors, a safety sensor, etc.). ), processor 122 may determine that one or more parameters have reached a dangerous level. Next, processor 122 alters the pressure and / or speed of the treadmill 112. For example, a coach could set a maximum speed parameter for individual 101. The processor 122 would ensure that that speed is not exceeded. The data storage can also be used to store previous returns and personal records for different protocols and the system 100 could allow the individual 101 to compete against previous personal records.

The data storage may also include various training programs based on the selection from the control panel 118. Next, processor 122 would guarantee non-harmful activity levels for individual 101 based on all variables. Data storage may also be able to record the performance and activities of individual 101, as well as storing any calibration data so that individual 101 does not have to go through the calibration process each time he uses the machine.

Fig. 2 is a block diagram schematically illustrating a system 200 for applying pressure to a lower portion 106 of the individual's body 101 according to another embodiment. System 200 includes chamber 102 and means 202 for adjusting (raising or lowering) and maintaining pressure inside chamber 102. An example of means 202 is a negative feedback control system described below.

The means 202 for adjusting and maintaining the pressure inside the chamber 102 include an intake system 204, the control panel 118, the pressure sensor 120 and a processor 206.

The intake system 204 includes an inlet port 208 for receiving a gas (eg, air), a regulated pressure source 210 and an outlet port 212. Regulated pressure source 210 pumps gas from inlet port 208 to outlet port 212. The outgoing port 212 is also an inlet port to the chamber 102. The gas is pumped to and from the chamber 102 through the outgoing port 212. The air inlet flow is regulated through the regulated pressure source 210. The regulated pressure source 210 includes an adjustable valve to control the flow of gas through the outlet port 212. According to another embodiment, the regulated pressure source may include a pump having an adjustable fan blade size or fan speed. The gas flow rate can be adjusted by varying the fan speed or the size of the fan blades. A safety exhaust port (not shown) may be connected to chamber 102 to allow gas to exit chamber 102 in the event of an emergency or a system failure.

The processor 206 communicates with the control panel 118 and the pressure sensor 120 to control the regulated pressure source 210. An example of the processor algorithm 122 is illustrated in Figs. 3 and 5. In this configuration, the processor 206 receives an input from the control panel 118. For example, the inlet may include a desired pressure inside the chamber 102 or a body weight of the individual. The processor 206 operates the regulated pressure source 210 using a loop, a circuit or a negative feedback system as illustrated in Figs. 3 and 5. The processor 206 monitors the pressure inside the chamber 102 with the pressure sensor 120. Based on the measurements from the pressure sensor 120 and the input from the control panel 118, the processor 122 sends a drive signal to the regulated pressure source 210 to increase or decrease the gas flow through the chamber 102 to keep the pressure inside the chamber 102 as close as possible to the desired pressure received from the control panel 118. The pressure (positive or negative) inside the chamber 102 produces an upward or downward force on the individual 101, which results in a lighter or heavier sensation.

The processor 206 can also communicate with an exercise machine 112 housed inside the chamber 102. The processor 206 can receive input parameters from the control panel 118 for the exercise machine 112. For example, the exercise machine 112 may include a treadmill with a speed or an inclination adjusted by the processor 206 based on the pressure detected inside the chamber 102.

The processor 206 may also include data storage (not shown), such as a database that stores various executable programs that can be selected or programmed by the individual 101 or by an operator through the control panel 118. The data storage may include a data repository that can be used to control the system 200. For example, while receiving data from all sensors, the processor 206 can determine that one or more parameters have reached a dangerous level. Next, processor 206 alters the pressure and / or speed of the treadmill 112. For example, a coach could set a maximum speed parameter for individual 101. Processor 206 would ensure that speed is not exceeded. Data storage can also be used to store past returns and personal records for different protocols and the system 200 could allow the individual 101 to compete against previous personal records.

The data storage may also include various training programs based on the selection from the control panel 118. Next, processor 206 would guarantee a level of non-harmful activity for individual 101 based on all the variables. Data storage may also be able to record and record the performance and activities of the individual 101.

In 302, the processor receives user data (for example, a desired pressure) from the control panel 118 and sensor data from pressure sensor 120 (and other sensors - performance sensors that measure the performance of the individual - the stride frequency and the acceleration / deceleration of the individual, etc.). In 304, the processor compares the sensor data with the user data to determine whether to increase or decrease the pressure inside the chamber 102. According to another embodiment, the processor can also compare the user data, the sensor data with Various programs stored in a database. In 306, the processor generates a control signal to increase the pressure inside the chamber 102 if the pressure sensor data is less than the user data. In 308, the processor generates a control signal to decrease the pressure inside the chamber 102 if the pressure sensor data is greater than the user data. The process returns to 302, where a new measurement is received. For example, the system cycles through these negative feedback loops 100 times per second.

The flow chart 400 presents a loop, a circuit or a negative feedback system that constantly monitors the pressure inside the chamber 102 and adjusts the pressure inside the chamber 102 based on the monitoring. The negative feedback loop can operate at a high frequency in order to precisely control and stabilize the pressure inside the chamber 102. In 402, the processor 122 receives user data from the control panel 118 and about sensor data from pressure sensor 120 (and optionally other sensors). In 404, the processor 122 compares the sensor data with the user data to determine whether to increase or decrease the pressure inside the chamber 102. According to another embodiment, the processor 122 can also compare the user data, the data of the sensor with various programs stored in a database. If the sensor data is smaller than the user data, the processor 122 generates an actuation signal to control the non-regulated pressure source 126 at 406, and an actuation signal to decrease the opening of the pressure regulating valve 132 in 408. If the sensor data is larger than the user data, the processor 122 generates a drive signal to control the non-regulated pressure source 126 at 410, and a drive signal to increase the opening of the regulating valve 132 pressure at 412. The process returns to 402, where a new measurement is received. For example, the system cycles through these negative feedback loops approximately 100 times per second.

Fig. 5 is a flow chart schematically illustrating a method for operating the system of Fig. 2 according to another embodiment.

According to another embodiment, the processor 206 can also compare the user data, the data of the sensor with various programs stored in a database. At 506, the processor 206 generates a drive signal to increase the regulated pressure source 210 by increasing the gas intake flow to the chamber 102 if the sensor data is smaller than the user data. At 508, the processor 206 generates a drive signal to decrease the regulated pressure source 210 by decreasing the flow of gas admission to the chamber 102 if the sensor data is larger than the user data.

Fig. 6 is a flow chart 600 schematically illustrating a method for calibrating the system of Fig. 1 and Fig. 2 according to one embodiment. In 602, chamber 102 is inflated to a predetermined pressure. In 604, the weight of individual 101 is measured, for example, using a conventional scale. The measured weight can be communicated directly from the scale to the 122/206 processor or manually by entering it into the control panel 118. The process can optionally be repeated for several different predetermined pressures in 606. A relationship between the pressure and the actual weight of the individual 101 is generated by interpolation of the measured values and the predetermined pressure to 608 over the entire range of operating pressures of machine. Multiple measurement points may be desirable due to the nonlinearity of the system at lower body weights.
